refactor(editor): introduce MenuOrchestrator for menu management

- Added MenuOrchestrator class to handle menu construction and coordination, improving separation of concerns within the editor.
- Refactored EditorManager to delegate menu-related tasks to MenuOrchestrator, enhancing maintainability and clarity.
- Updated CMake configuration to include new source files for the MenuOrchestrator component.

Benefits:
- Streamlines menu management, leading to a more organized and efficient user experience.
- Enhances the overall architecture by clearly defining roles for menu handling and editor operations.

+ * - Session-aware menu updates
+ * - Menu state management
+ * 
+ * This class follows the Single Responsibility Principle by focusing solely
